my sculpting tool is kind a hard to use, anybody knows how to change?
I didn't understand your question. Are you looking for better affordable options than stylus? I recommend you the wacom intuos pen &amp; touch art. But unless you just want to sculpt in blender or to digital painting you will rarely need it I guess. I have the small model and I can't complain.
